Direction of digitizing

For classifier objects the user can appoint a direction of digitizing.

The direction of a digitizing may be:

- arbitrary;

- predefined;

- lower right ;

- counter-clockwise (object at the left);

- clockwise (object on the right).

For polygon objects the directions of digitizing can has following values: object at the left (detour of object counter-clockwise: it is used for reservoirs and deepenings of a relief) and object on the right (detour of object clockwise).

For linear objects it is possible to use on the right above (for contours and elements of a relief), predefined (for those objects for which it have meaning to distinguish the beginning and the end of the metrics, for example, the rivers are digitized from a source to a mouth) and arbitrary for all other cases.

Point objects have only an arbitrary direction of a digitizing.

All others objects have arbitrary or predefined direction of a digitizing.

Multicontour object

If option the Generalization of multicontour objects is selected in Map Sorting, then for RSC classifier objects that have the Multicontour property, additional object contours will be built by generalization method.

Additional contours are formed for smaller scales of display - 1/4, 1/16, 1/64 of the base map scale and are recorded into the map metric along with the main contour.

When the map is compressed, those contours of objects that are closer to the current display scale will be automatically displayed.

This speeds up the display of complex objects and makes the image of the area more visual.

During any editing of the map and when performing calculations according to the metric of the object, the main contour of the multicontour object is processed.
